Plate tectonics “Quest”: Wednesday March 28, 2012
THIS WILL COUNT AS YOUR FIRST GRADE IN THE 4TH MARKING
PERIOD!
You may use your plate tectonics map and ladder method as reference
sheets.
 All of Chapter 1- Plate Tectonics
 Ocean Explorations that support seafloor spreading (Glomar
Challenger/ JOIDES Resolution)
Earth’s Interior
 Vocabulary- will be either in a multiple choice or fill-in.
o seismic waves, pressure, crust, basalt, granite, mantle, lithosphere,
asthenosphere, outer core, inner core
 Label diagram- of Earth’s interior
o Inner core, outer core, mantle, crust, lithosphere, asthenosphere
 Compare and contrast oceanic crust and continental crust
Convection and the Mantle
 Vocabulary- will be either in a multiple choice or fill-in.
o radiation, conduction, convection, density, convection current
 Know how heat from Earth’s interior is the driving force of plate tectonics.
Drifting Continents
 Vocabulary- will be either in a multiple choice or fill-in.
o continental drift, Pangaea, fossil
 Know the evidence that supported the hypothesis of continental drift:
matching coastlines from continents, similar land features, evidence from
fossils, and evidence from climate.
Sea-Floor Spreading
 Vocabulary- will be either in a multiple choice or fill-in.
o Mid-ocean ridge, sonar, sea-floor spreading, deep-ocean trench,
subduction
 Evidence for Sea-Floor Spreading (from textbook)- eruptions of molten
material, magnetic stripes in the rock of the ocean floor, ages of rocks
Ocean Explorations (study from your handouts and ISN notes)
 Glomar Challenger 1968- drilled sediment core samples east and west of
the Mid-Atlantic Ridge.
o Evidence supported seafloor spreading- age of sediments were older
further from the ridge and sediments were thicker further from the
ridge
 JOIDES Resolution 1996- drilled sediment core samples east of the Juan de
Fuca Ridge and used sonar.
o Evidence supported seafloor spreading- age of sediments and
sediment thickness (thicker further from the ridge)
The Theory of Plate Tectonics
 Vocabulary- will be either in a multiple choice or fill-in.
o plate, plate tectonics, scientific theory, fault, divergent boundary, rift
valley, convergent boundary, transform boundary
 Types of plate boundaries: you will have a data table to fill out that will
include:
o Type of boundary
o How the plates move
o What geologic feature is formed at this type of boundary?
o Name an example using your Tectonic Plates map.
o Name the tectonic plates that were involved in the example you chose.
Calculating rate
 Rate = distance/ time
